Got the GTX 670 today and was so excited getting it plugged into PC. Turned it on and then spent the rest of the day wrestling with the computer to make it work properly.
I’ve since installed the latest build available, CUDA Toolkit 4.2, the latest Nvidia Beta drivers for the card and then the 2.64 build of Blender which eventually made it the most stable even though it’s still a mess.
Get various CUDA errors while rendering with Cycles in the preview window, sometimes the preview won’t start, sometimes it stops in the middle and sometimes it just keeps going indefinitely. Blender itself just seems to run alot slower, moving around the viewport is often stuttery, especially so when the preview window is rendering. On several occasions it has crashed the program completely so I’m saving more often than normal now(which was already every minute or two!)
Hitting F12 seems to work now but everytime it finishes a sample, the system hangs, the top menu bar adds the (Not Responding) text as if it’s about to crash, then continues as normal. I’ve left it on overnight to do a full render of something that should take about 12 hours so I’ll see if it’s managed it when I get into work tomorrow or not or crashed in the middle of it.
I don’t know what else to do or try. Hopefully there will be a fix for it all soon but it’s went from a perfect experience with just slow rendering on the CPU previously to behaving like a dog now with lightning quick renders when it works.
Anyone else had similar problems or even managed to solve them?
